I think if the target demographic is locals, then December is the better late night trade - as most people don't go away until AFTER christmas. January is the time most families etc go away, and who wants to holiday in Eastern Creek? I think thats more the point of the January trading hours.
That said they'll probably adjust as demand appears.
I will say though - that Fred (like many other passholders) will be getting very upset right now, about a product they purchased in advance, sight unseen, after accepting all the terms and conditions.
It's like buying an apartment in a high-rise 'off the plan' before ground has even been broken. You do so at your own risk - you've agreed to the terms and conditions, knowing full well that:
a) the park was a seasonal park and would fluctuate it's operating schedule from year to year
like ANY park, operating hours (and attraction operating hours inside the park) are subject to change without notice.
Potentially, if you're unhappy with this Fred, you can seek a refund for item not as described, and at this stage, they'd probably give it to you. But no doubt, you will choose to accept these terms and hours, and continue to use the pass, in which case you probably aren't THAT unhappy about Western Sydney finally having a source of entertainment for 6 months of the year.
Enjoy the park Fred.
THERE'S A WORLD I'D LIKE TO LIVE IN, A WORLD I'D LIKE TO SEE
WHERE'S THERE'S TOO MUCH FUN FOR EVERYONE, AND STILL LOTS LEFT FOR ME
WHERE THERES MAGIC ON EVERY CORNER, AND A SMILE ON EVERY FACE
IF I COULD JUST GET OUT OF THIS PERFECT DREAM, INTO THIS PERFECT PLACE...
Wouldn't It be Wonderful, If the World Still Had Wonderland?
